GRINDING AND POLISHING WHEEL.

SPECIFICATION forming part of Letters Patent No. 527,196, dated October9, 1894.

Application filed February 14, 1894:. Serial No. 500,111. (No model.)

To all whom it may concern.-

Be it known that I, FRANK E. GUDELL, a citizen of the United States,residing at Cleveland, county of Guyahoga, and State of Ohio, haveinvented certain new and useful Improvementsin Grinding and PolishingWheels, of which the following is a specification.

This invention relates to wheels for grinding and buffing or. polishing,and consists of a loose belt attached at one or more points on theperiphery of the wheel, which, when the Wheel revolves will spread andkeep clear from the periphery of the wheel by the centrifugal force, theobject of which is to provide a cushioned grinding and polishing surface on the wheel, the purpose of which isto give to the belt a yieldingfaculty, so that when an article is held against saidbelt for grindingor polishing, the belt will not cut into or injure the article. Thebelts may have a scratch-brush, emery or buffing surface, and are madedetachable for removal and replacement.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a wheel having a belt attached in themanner above stated, showing one means of securing the belt. Fig. 2 is aside elevation of a wheel having a belt attached in a plain or simplemanner, and showstho wheel at rest and the belt seen loose in its normalposition. Fig. 3 is a similar side elevation, showing the wheel asrevolving and the circle of the belt extended at an equal distancearound the wheel, except at the point of attachment, by the centrifugalforce of the revolving Wheel.

A represents a disk or wheel made of wood or other suitable material,having an eye at its center for attaching it to a mandrel.

B represents a band or belt loosely surrounding said wheel, the endsabutting and secured by screws or other detachable means. In Fig. 1 araised place or block 0 is provided for attaching the ends of the beltonto, which, when the wheel revolves will fill out the full circle ofthe belt as the belt extends from the wheel by the revolutions of thesame.

In Fig. 3, where the belt is attached to the periphery of the wheel,when the wheel is revolved, there would be a short depression in thebelt at that point.

The block 0 in Fig.1, may be made of rubher to form a flexible orcushioned projection that would yield to the pressure of the articlebeing polished, in like manner to the belt, and thus maintain a uniformcushion effect throughout the whole circumference of the wheel.

The belts may be of any desirable widths and coated with any of thegrinding and polishing materials.

Having described my invention, I claim- In grinding and polishingwheels, the combination' with wheel A, of a loose belt B attached at oneor more points to the periphery of the wheel, whereby the centrifugalforce of the revolving wheel extends the circle of the belt,substantially as and for the purpose specified.
